針對近α型Ti600鈦合金熱加工抗力大、變形困難等問題，通過對實驗樣品分別進(jìn)行5種不同氫含量的置氫處理和真空退火除氫，研究熱氫處理過程中Ti600鈦合金的組織結(jié)構(gòu)演變和高溫力學(xué)特性，探討熱氫處理對鈦合金組織和高溫力學(xué)行為等熱加工工藝塑性的影響規(guī)律。

Aiming at the problems such as large deformation resistance and difficulty in deforming during hot working of high-temperature α alloy Ti600, all specimens were handled hydrogen treatment respectively by five different hydrogen content (mass fraction) from 0.1% to 0.5%, and dehydrogenated by vacuum annealing. The microstructure evolution and tensile properties of Ti600 alloy at thermal temperatures were studied. The effects of thermo-hydrogenation treatment on the microstructure, grain size, as well as high temperature mechanical, heat processing plasticity and the variations regularity were investigated. The result shows that the microstructures of Ti600 alloy are refined to some degree. The thermal plasticity of Ti600 alloy is improved obviously with hydrogen increasing from 0.1% to 0.5%.
